Well done. You have reached point A and found the QR code!
At point A, take a group photo with all team members and the bandanas visible, with a recognizable background.
You can find point B here:
52.22611 5.22119
At point B, you are looking for a white document with information on how to open the cryptex.
Inside the cryptex is a unique code, which you need to bring back to the starting point.
Still all within 90 minutes.
Good luck!
The hunters are coming for you!
